About DNS Lookup
DNS Lookup solves a specific problem that comes up daily for anyone dealing with privacy checks: doing it once, fast, without an account. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It pairs naturally with the other utility utilities here when you need to chain a quick workflow.
